آمَنَ الرَّسُولُ بِمَا أُنزِلَ إِلَيْهِ مِن رَّبِّهِ وَالْمُؤْمِنُونَ ۚ كُلٌّ آمَنَ بِاللَّهِ وَمَلَائِكَتِهِ وَكُتُبِهِ وَرُسُلِهِ لَا نُفَرِّقُ بَيْنَ أَحَدٍ مِّن رُّسُلِهِ ۚ وَقَالُوا سَمِعْنَا وَأَطَعْنَا ۖ غُفْرَانَكَ رَبَّنَا وَإِلَيْكَ الْمَصِيرُ (285)
(2:285) The Messenger has believed in the Guidance which has been sent down to him from his Lord, and those who believe in the Messenger have also sincerely accepted the same. They all believe in Allah, His Angels, His Books and Messengers. And they say, "We do not discriminate against any of His Messengers. We have heard the Message and submitted to it. Our Lord, we look up to You for forgiveness, for to You we shall all return." *337
*337). This verse outlines what one is required to believe in and what should be the distinguishing characteristics of one's conduct. They consist of the following: belief in God, in His angels, in His Books, in all His Messengers (instead of some rather than others), and in the fact that ultimately one will have to stand before God's judgement. These are the five fundamental articles of faith in Islam. Having accepted them, the only proper attitude for a Muslim is to cheerfully accept and follow whatever directives he receives from God. Instead of exulting in his moral excellence he should be humble and should constantly seek God's forgiveness and mercy.
